Here is his idea:

Interested to see really how the block shed rating is determined for top run stuffing and elite pass rushing defensive linemen.
It's widely accepted that any R^2 value 0.80 or higher is a strong correlation. The closer the R^2 is to 1.0 or -1.0, the stronger the relationship. The closer the R^2 value is to 0 the weaker the relationship.
You can see this data set has an R^2 of 0.7714. While not over 0.80, there is still a clear positive correlation. Some might argue it's a strong correlation even though it's slightly below the 0.80 benchmark. For more information on this type of statistical analysis check out this link: http://mathbits.com/MathBits/TISection/Statistics2/correlation.htm
So what does all of this information tell us? Honestly, it's does tell us much. After going through all of the attributes and statistics I can't find anything truly consistent about how the "Madden ratings team" assigns the BSH attribute. I do believe the strength attribute plays a part, but it's not as much of a factor when you look at players with a lower overall. Strength is used by EA to manipulate the OVR ratings of some players, especially DT's. Both awareness and strength are tied as the #1 factor in the Defensive Tackle overall (OVR) formula. BSH, PMV, and FMV, are all tied as the 2nd most influential attributes in the OVR formula for DTs. So, both STR and BSH can be used to reward or penalize a defensive tackle, even if it's not a true representation of the actual NFL version of that player.

Can an NFL player be strong, but not excel at shedding blocks? I believe the answer is clearly, "yes". Shedding blocks is not all about strength. With good technique a weaker player can shed blocks. There are several techniques that defensive lineman learn to increase there chances of shedding a block.
Out of curiosity, I wanted to know how much the BSH attribute factors into simulated seasons and gameplay. I simulated three seasons with the NY Giants (Year 1 for all three, with the same schedule). First I turned the BSH attribute down to 0 for all of their DE's and DT's. I didn't change any other attributes. I turned injuries off, because I wanted the same players to be available for all three seasons.
After the first season, not one player on the defensive line recorded a sack. That's right, zero sacks for the defensive line with the BSH attribute at zero.
I restarted the franchise for the next simulated season. I turned the BSH attribute up to 99 for all of the defensive lineman. Again, I didn't change any other attributes. This time the defensive line accounted for 38.5 sacks.
For the third and final simulation, I restarted the season and turned the PMV and FMV up to 99 for all of the defensive lineman and set the BSH attribute to 0. Again, the defensive line did NOT record a single sack and they only accounted for 9 total tackles as a group. WOW.
Some people tell me that attributes don't matter. I believe several attributes matter and for simulation purposes, BSH plays a huge role in the both sack and tackle statistics. I know this was a drastic comparison by using 0 and 99, but it was the quickest way to see if there was an impact.
On top of the simulated seasons, I played 3 games against the CPU, one with each of these attribute settings. I even picked a horrible team to play against (Jacksonville), just to give my 0 BSH defensive line a chance. In the end, the 0 BSH teams had a very difficult time. They gave up a lot of big runs to MJD and put very little pressure on the QB. I even controlled several of my lineman and had very little success getting off the block. When I played with the 99 BSH team, they not only applied more pressure to the QB, they played the run much better.
The point with this experiment, is that having realistic (accurate) BSH ratings should be a priority for the ratings team. I believe this attribute is one of the most important for defensive players and it should be as accurate as possible. Players like Peppers and Mathis are not nearly as effective as they should be, due to having a poor BSH attribute. This needs to change.
So how should the BSH attribute be rated? First and foremost, the "Madden ratings team" needs to be expanded so evaluators can watch more game tape. In my opinion, watching tape and reviewing the best available statistics will produce the most accurate and consistent block shed ratings. The ratings team needs to be expanded not only because there is limited time between roster updates, but also by having more people involved will reduce bias. BSH is also an attribute that should NOT change week to week. I believe a player can improve, but this attribute should not be used just to manipulate a player's OVR rating. Accuracy and consistency in player ratings should always be the priority, regardless of the impact on OVR.
I would like to thank Clifton for his great idea and I hope I was able to shed some light on the BSH attribute. Hopefully, the Block Shed attribute can be more accurate and consistent when it comes to Madden 13 player ratings.
